Need help guys!

Ok so here I have auto fem seed which I topped 4 days ago which I later I read I should not have done due to the fact you shouldn't top auto plants...anyways she's on day 42 since breaking ground she's got plenty of nodes as you can see she's 8.2 inches tall and I'm about to go 12-12 any input would be greatly appreciated!!

Not 100% it's auto fem I'm pretty sure it is though its a Dinafem blue Thai . Also want to take cuttings , have the rock wool just need to watch a few vids first. It's 8 inches tall MAIN QUESTION how much can I expect to harvest from a 12 inch plant when it's ready???

Eight inches at over a month old is pretty small IMO, and no need to switch timing if it's an auto.

Hey man thanks for replying so quick , I agree its small for a month+ and the thing is I'm not 100 percent sure shes auto so should I hold off on changing the light schedule and leave her on 18-6 ? Best case scenario she grows more (I have a two feet enclosure) and if it auto it will just flower automatically when it's bigger or should I change the light schedule now and hope it flowers . How much can I expect to get from it if its 12 inches? If its auto should it have been left on 24/7?

I think I was checking out the blue thai and I'm pretty sure the one I was looking at was NOT auto, in which case you might be wise to flip to 12/12 in the next couple days. From a 12" plant you would probably get about 1-7g. Good luck!

Did some reading its not an auto flowering plant so 12 12 it is!
